Question 1. Two Goats Are Tied With A Rope Of Length 40m Outside Of A Rectangular Shed Of Dimensions 50m X 30m. The Goats Are Tied To Different Corners Which Lie On The Opposite Ends Of A Diagonal Of The Shed. What Is The Area In Which The Two Goats Can Eat Grass, If They Choose Not To Eat In The Common Aproachable Area?

Answer :

Given rope of duration = 40m (radius) 

Area of semi circle =(pi*r^2)/2 = (1600 * pi)/2 = 800*pi ---(1)

Area of quarter circle = (half of * 800 * pi) = four hundred*pi ----- (2)

Area of area is = r*r*(pi/2)/2 = 25*pi ----- (three)

By adding above eq. (1) (2) & (three)

Total place = 1225*pi

As according to quesiton there are 2 goats

so place = 1225*pi*2 = 2450pi.

Question 2. In A Society Of 80 Resident Families Who Subscribe Newspapers, 60% Of Them Subscribe The Hindu Newspaper, 80% Of Them Subscribe Regional Language Newspaper And 70% Of Them Subscribe Toi. How Many Families Could, At The Least, Be Subscribing To All The Three Newspapers?

Answer :

Total no. Of families who take newspaper=eighty

Hindu newspaper = 60% = (eighty*60/one hundred) = 48

Regional newspaper = eighty% = (80*eighty/one hundred) = 64

TOI newspaper = 70% = (70*eighty/one hundred) = fifty six

Find commonplace households take H.C.F (forty eight,64,fifty six) = 8

Therefore,(eight/eighty)*one hundred=10%

So, commonplace families who take all newspaper = 10%.

Question four. A Father Is 30 Years Older Than His Son However He Will Be Only Thrice As Old As The Son After five Years What Is Father's Present Age ?

Answer :

Lets count on son's age = x

So, father's age = x + 30

After 5 years:

Son's age = x + 5

Father's age = x + 35

In 5 years the daddy is thrice as vintage as his son so:

3(x + five) = x + 35

x = 10

So, present day father's age = 40 Years.

Question five. A Person Travels In A Car With Uniform Speed. He Observes The Milestone,which Has 2 Digits. After One Hour He Observes Another Milestone With Same Digits Reversed. After Another Hour He Observes Another Milestone With Same 2 Digits Separated By 0. Find The Speed Of The Car?

Answer :

Let 10'splace digit is x and unit's region digit y

First milestone : 10x+y

Second milestone : 10y+x

Third milestone: 100x+y

Since the velocity is uniform so

Distance covered in first Hr = Distance covered in Second Hr

(10y+x)-(10x+y) = (100x+y)-(10y+x)

By fixing,

y=6x 

but considering that x and y are digits so simplest possible aggregate is x=1 and y=6,

So common pace = forty five Kmph.

Question eight. A Cylinder Is 6 Cms In Diameter And 6 Cms In Height. If Spheres Of The Same Size Are Made From The Material Obtained, What Is The Diameter Of Each Sphere?

Answer :

The quantity of the cylinder is Pi x r^2 x h = Pi x 3^2 x 6 = 54Pi 

Volume of a cylinder is 4/three x Pi x r^3 

Now 54Pi = 12 x 4/three x Pi x r^3 

fifty four = sixteen x r^three 

r^three = fifty four/16 = 27/8 

r = 3/2 

Therefore diameter is three cms.

Question nine. A Survey Of A Village Showed That 1 / 10 Of The Total Population Speak Neither Hindi Nor English. 1 / five Of Them Cannot Speak English And three / 7 Of Them Cannot Speak Hindi. What Percentages Of People Know Only One Language?

so total humans speak both = 4/five + 4/7 - 9/10 = 33/70

men and women speak any = 1 - 33/70 - 1/10 = three/7

% = 300/7% = 42.86%.

Question 13. If M^2+m^-2=23;then What Is The Value Of M^3+m^-3?

Answer :

m^2+m^-2=23

=> (m + m^-1)^2 - 2 = 23

=> (m + m^-1) = 5

m^3+m^-3 = (m + m^-1)^three - three(m + m^-1) = 5^3 - three*5 = one hundred ten.

Question 14. If M=2- _/3 Find The Value Of: M^6+m^5+m^four+1)/m^3?

Answer :

m = (2 - ?Three)

=> 1/m = (2 + ?3)

(m^6+m^5+m^four+1)/m^three

= m^three + m^2 + m + 1/m^3

= (m + 1/m)^three - 3(m +1/m) + m(m+1)

= 4^three - 3*4 + (2-?Three)(3-?Three)

= sixty four - 12 + 9 - 5?3

= (sixty one - 5?3).

Answer :

Let's call the peculiar quantity 2a+1, wherein a is an integer.

Then (2a+1)^2 = 4a^2 + 4a + 1 = 4a(a+1) + 1.

Since a is peculiar, a+1 is even.
